Domestic car manufacturing is weak, what does it have to do with our land tanks?

Speaking of rockets, they have been a”consumable item” since the very beginning of their development and design.

Some rocket engines are designed to have a lifespan of only one time during their development and manufacturing.

After all, this thing cannot be recovered.

It is better to directly burst the thrust to the maximum and maximize the fuel power!!

Needless to say, other parts and materials themselves are all based on a one-time service life, and the purpose is to send satellites and space stations into the sky.

It is only in recent years that both aerospace materials and processes have improved.

Stronger rocket engines can also ignite several times. In addition, in order to achieve the recovery and reuse of launch vehicles, several major aerospace powers have figured out how to enhance the durability of the body and internal parts of the engine.

Otherwise, according to the previous standard of one-time life of”consumables”, that kind of thing will have no value if you recycle it.

The rockets that Hongqi is going to make use of self-developed aviation special steel and aerospace special aluminum alloys. In addition to the process and design produced by the system, they can be recovered after launch for normal body maintenance.���, repair wear and tear 887, and replace the rocket engine after a fixed number of launches.

According to estimates, the recovery life of a single rocket can be extended to hundreds of times.

Even if something goes wrong in the middle of the journey, it is not a problem to recover thirty or fifty times.

This value is revealed, it will be terrifying!

In an instant!

All the astronauts present had their eyes wide open!

Almost gasped!!

“Hiss hiss hiss!!!”

……

“Hundred times recycling?!!”

“”Can your rocket body design be so strong? How many times can the engine ignite? How long!”

Immediately.

Ding Ke, director of rocket assembly, also widened his eyes!

After all, he is specifically responsible for this aspect in the First Academy of Aerospace.

The regenerative cycle hydrogen-oxygen engine currently carried on the Long March 5 has a cumulative life of 8 times, with a total time of 4,000 seconds, which is nearly 1 hour and 7 minutes.

If it exceeds this number, even if the rocket engine is not damaged, it must be replaced as a whole to avoid wear and tear of the internal non-combustible power chamber and take-off accidents.

If it is a solid rocket engine, the life will be even shorter.

Because solid rocket engines have a simple structure and can only be used once after ignition.

Its working time is usually less than 1 second at the shortest and less than 100 seconds at the longest.

However, it has the characteristics of large specific impulse and strong explosive power.

It is currently usually used to provide explosive thrust in the ignition and take-off stage, and then combined with liquid core rockets to go to the sky.

The current single-use liquid rocket engine can work for hundreds to thousands of seconds, with a large and adjustable thrust range, and can be recycled and reused repeatedly.

Naturally, it is the first choice for current spacecraft.

“The ignition life of the Hongqi rocket engine should be more than 30 times, and the cumulative life time should reach 15,000 seconds, which is nearly four hours. Of course, this is only the loss of life without accidents, and the internal fuel must be repeatedly refilled.……”

“In addition, the super-cruise rocket recovery device actually uses the heavy rocket to land, adjust its attitude in the air orbit, deploy the landing bracket, and then use the ground to launch a small cruise rocket, which combines with the heavy rocket in the air for recoil boost.……”

“The reason why heavy-lift launch vehicles and super-heavy-lift launch vehicles are difficult to recover and land is that they are too heavy and are affected by atmospheric pressure and gravity.

It is difficult to grasp the timing of secondary ignition and adjust the landing attitude data accurately.

Now that we have the external force intervention of the airborne patrol device, the recovery of the entire launch vehicle can be more controllable, and the timing of secondary ignition will not be extremely harsh.

”

“As long as nothing goes wrong, the recovery rate will be at least 95% or more.” (To read the exciting novels, go to Faloo Novel Network!)

Lu Yan said.

In fact, the rocket recovery method currently used by major space powers is to perform a secondary ignition to adjust the attitude during the rocket landing process, and then let the rocket use the reverse thrust in the air to eliminate more than 95% of the impact force, unfold the support bracket at the bottom of the rocket, and finally land on the ground.

It is equivalent to simulating an ignition takeoff in the air, but this time it is for a smooth landing.[]

This set of methods is of course no problem for small rockets.

Because small rockets have a small mass and a small size, they are easier to control.

However, heavy rockets and super-heavy rockets use this method.

The overall difficulty will increase exponentially.

It’s like asking a slim gymnast to do a 360-degree flip in the air, and asking a 300-pound fat man to do the same 360-degree flip gymnastics in the air. Can the difficulty be the same?

The design of the super-heavy launch vehicle alone, the entire tonnage and volume mass, has already approached the current limit of human aerospace level. Many aspects are concessions to achieve the greatest capacity in human history.

The entire body material load is also large. To ignite the secondary ignition in the air, not only the timing and precise electronic control must be accurate, but also the attitude adjustment must be perfect under the atmospheric pressure and the reverse thrust of the secondary ignition. Under such complex and extremely harsh working conditions, if there is any problem, it is good not to disintegrate and explode in the air.

And the idea of Hongqi here.

In fact, it is a combination of the existing secondary ignition landing idea, and the external force-assisted patrol rocket is combined with the heavy rocket body in the air to undertake the landing of the heavy rocket, which is equivalent to using a special small rocket to undertake the recoil pull and adjust the air posture of the body.

It sounds a bit incredible!! It is exactly the same as the idea of fighter jets refueling in the air!!

If you are not careful, the collision of rockets will be a”big firework”!!

After all.

During the flight, the small rocket must be combined with the heavy rocket in the air!!

How can this be done? ?

It’s exaggerated to think about it!!

But Hongqi has the most advanced air patrol algorithm in the world, as well as the ability to build the strongest chip supercomputing platform, to calculate and adjust the remote control of multiple rockets at the fastest speed, and to perform precise operations in the atmosphere!!

As long as this idea can be realized.

The entire recovery rate will naturally rise. After mature use, the difficulty of secondary ignition control of heavy rocket recovery can also be reduced to a minimum.

After listening to it.

The aerospace people present, including Gong Nanjiang, were stunned again!

A sentence has emerged in their minds.——

“crazy……”

“No, it’s a genius idea!!”
